SKF this type of bearing do you understand?

SKF CARB® Toroidal roller bearing is a new type of radial spherical roller bearing. Developed by SKF company himself, and to the market in 1995.     CARB bearing function with automatic self-aligning spherical roller bearing, cylindrical roller bearing axial displacement characteristics, have needle bearing compact cross section. Have a look, is this appearance.     The structure of the bearing is designed for a floating end support. For single roller bearings, bearing inner and outer ring raceway surface is concave cambered surface, the symmetry of the roller, roller with a convex surface inside and outside the ring to stop the axial displacement between each other. Optimization of raceway and roller contour surface, make the bearing load can be evenly spread, reduce the friction in the process of operation.     CARB bearing roller can automatically guide, whether inner ring can be related to the outer ring axial displacement or to not in ideal condition, it can be in a uniform load acting on the position of the roller. Even in the presence of Angle error or axial displacement, can also have a bearing on abundant bearing ability, thus product has long life.     CARB bearing the main construction methods for belt on frame and roller. , of course, these two kinds of structure of the product to be able to have open and with seals.     CARB bearing inside diameter of the hole has a straight hole and cone hole, straight hole of the bearing can be directly installed on the straight shaft; On the cone shaft taper hole of the bearing can, also can with shaft sleeve is installed on the straight shaft. Shaft sleeve can choose tight sleeve and sleeve.     CARB bearings with radial clearance of ordinary group, but the big local products have been provided in three groups of radial clearance.     Must pay attention to, straight hole and cone hole radial clearance value is not the same! ！ ！ Products of the same size, of course, the cone hole bearing radial clearance must be greater than the straight hole bearing. Detailed numerical to look down the left left left bore cylindrical CARB bearing radial clearance cone CARB bearing radial clearance & emsp;   CARB bearing and one of the biggest feature is the axial displacement, the displacement is for shaft in operation after a certain time thermal contraction. Axial displacement in is given in the product list, the axial displacement reference is given in the table in the bearings have a large enough work clearance between inner and outer circle and no Angle error when applicable.     S1: with insist or roller bearings, full of when the axial position to deviation from the direction of the buckles, allows the axial displacement of the reference & emsp;   S2: sealed bearing, when axial to tend to the direction of the buckles, allowing the axial displacement of the reference & emsp;   CARB bearings allow inside and outside the circle there is between 0. 5 degrees of Angle error, within the scope of this Angle, will not affect the bearing performance of a bearing. When have larger axial displacement, allowing the Angle error would be reduced; Angle error can make the roller axial displacement to a certain extent, make it close to the end of one of the bearing, the greater the Angle error, allowing the axial displacement should be reduced. The greater the Angle error, the friction will increase with it. Bearing, even still accept Angle error can also be reduced. If the guide bearing is made in brass insist on frame, Angle error are not allowed to go beyond zero. 5 degrees. Remember to keep in mind, Angle error in 0. 5 c is applied, the life of the bearing is assured, greater than zero. 5 degrees, the use of the bearing life is very short.     （ The above content for hk bearing network bearing technical engineers to write, please leave a message if you have any questions. ）     Hk united bearing focus bearing industry informationization service nearly 20 years, with many excellent bearing enterprises grow together, also witnessed China's bearing consumer technology from low to high development process. We will adhere to continue, the steadfast work, don't, don't give up, to the benign development of Chinese bearing industry do some thinning.
